Have been working off ‘n on with this Distro since about 9-10 days ago, and it’s been sorta like chasing one of those women who *WON’T* let you stop chasing her…so to speak of such ‘Thangs. However, it’s also been like driving one of those ‘Muscle Cars’ from their peak 1964–1970 era, that slams you back into your seat, thrilling you with their power ‘n speed, and yet providing you with a blown engine if you make one mistake.
CentOS is headed to the #3 spot on Karmi’s Top 10 Linux Distros page by offering an option to opt out of the Linux ‘Pesky‘ Passwords, and being my new favorite Enterprise Class Operating System. Business and/or Home OS, but my focus is on its home Desktop/Workstation ability. There have been plenty of ups ‘n downs whilst testing this OS, especially with full installations to 32 GB USB’s, and those problems limit its portability to SSDs, at this point; however, last night I ordered a FIT Plus USB 3.1 Flash Drive 128GB (on sale for $24.99 w/ free shipping) in hopes of the larger size resolving the USB Portability issue.
The CentOS-8.2.2004-x86_64-dvd1 ISO is 7.66GB, which causes problems when creating installation media and attempting to do a full install to USB, IMHO. There is a much smaller ISO version, but mainly used for “network installations,” I believe. I tried them both, but after 9-10 days with many failed attempts, I honestly don’t remember all that has happened (was also testing Fedora, Mint and openSUSE during that time!?). However, going to a 32 GB so-called ‘Live’ USB installation media (I never saw ‘Live’ – just “Install” and/or “test media and Install” options…no actual ‘Live’ USB testing of CentOS) over the normal 16 GB USBs I use seems to have fixed my USB installation media issues. Did try a full install to a 64 GB DataTraveler USB, but problems started showing up soon after installation, e.g. updating problems, USB portability to other computers, and finally just froze. SanDisk & Samsung are the only two brands of USBs that I have found success in doing full installations too…many other brands seem to have problems with the Linux ext4 format, IMHO. CentOS has an unusual partitioning format that seems focused on the “lvm2” partitioning. Here’s a pic:
That’s on the temporary 128 GB SSD I am using to test it. That unallocated 7.45 GBs at the end is because I first installed it onto a 120 GB SSD, then made an image using Clonezilla, and then restored that image to the main testing SSD. Restoring backup images to a disk requires a disk of the same size or larger. On any size disks (so far) that LVM2 partition takes up almost the entire disk…beyond my understanding, but LVM2 (Logical Volume Manager) seems to need lots of space. Fedora uses that same LVM2 partitioning, but its ISO was only 1.92 GBs, which may be why it works so well on the 32 GB SanDisk USB. If CentOS works on that 128 GB USB I just ordered then I will also add the ‘Portability’ category to its ranking. Just such a smooth OS (when issues are corrected, e.g. too small of a disk) that offers the option to opt out of the Linux ‘Pesky‘ Passwords – gotta Love it!
A ‘Reminder’ that I have started managing the blog’s Media Library content a little closer, and will be reusing pics when I can help save space. Here’s an example of reuse:
That’s from the Fedora Cinnamon/KDE Plasma SPINS – ‘Require a password to use this account’ post, but CentOS has the very same setting’s setup that offers the option to opt out of the Linux ‘Pesky‘ Passwords.
Yesterday, I decided to try installing CentOS to a 120 GB SSD, using a 32 GB USB installation media, and have not had issues…just an excellent Enterprise Class OS ‘Desktoping’ experience. Hardware recognition has been excellent…beyond the too small USB usage. CentOS doesn’t recognize exFAT or NTFS formats, so far (may be older Kernel). Here are some pics from 3 different computers…first from the ‘Apevia’ Ryzen™ Linux test computer:
Here is the system info on ‘InWin’ Linux test computer:
And here is ‘Ace’ the Laptop’s system info:
I had to use a USB 3.0 SATA Docking Station because ‘Ace’ the Laptop didn’t fully recognize the SATA to USB Cable with UASP that was attached to the SSD. Used that same cable to test CentOS on the ‘Rose’ and another computer, so it was ‘Ace’ the Laptop not knowing how to handle an OS on it. Have used that same cable on ‘Ace’ to do an image backup of WIN10 to a SSD, and also for adding data to, but the OS confused it.
CentOS comes with a KDE choice, but KDE Plasma is just too ‘Busy’ for me, and I went with the GNOME choice this time.
Here’s the Dock view (you have to open it which I don’t like):
GNOME offers so much customizing, setting’s options, app choices ‘n Gnome extensions, etc. that I generally end up going with Dash to Panel, and then the Arc Menu extensions for that Windows and/or Cinnamon look.
Here’s the Arc Menu opened, and the Power Off button finally easily added to the left side (one stays on the right side also):
The installer is almost exactly the same as Fedora’s was, Fedora 32 – ‘Linus Torvalds’ Linux Distro Choice’ has most of those pics up. Not for Newbies, but most Linux users could probably figure it out with a little effort.
Basically, CentOS is the ‘Free Version’ of Red Hat Enterprise Linux, which makes CentOS one of those Distros that I called “well *SUPPORTED* (for the long-term) Linux Distros that are also known for their reliability ‘n stability.” It is definitely a *REAL* serious Operating System!
(Note: I may add an update to the bottom here after that 128 GB USB arrives next week, so check back if you’re interested in the portability of USBs.)
Rule of Thumb – if you can’t install Ubuntu on it, then you can’t install any Linux Distro on it.
