installation

[Patrick Dupre]

Hello,

Can this partitioning/formatting be a problem:
    mke2fs /dev/sda6 -t ext4 -b 2048 -L boot0
    mke2fs /dev/VolGrpSys_DK0/root_usr -t ext4 -b 2048
    mke2fs /dev/VolGrpSys_DK0/usr_local -t ext4 -b 2048
    mke2fs /dev/VolGrpSys_DK0/usr_lib -t ext4 -b 2048
    mke2fs /dev/VolGrpSys_DK0/usr_src -t ext4 -b 2048
    mke2fs /dev/VolGrpSys_DK0/tmp -t ext4 -b 2048
    mke2fs /dev/VolGrpUsr_DK0/home -t ext4 -b 2048
?

Then the mount point is on / (root_usr)

Thank.

A separate partition for /usr might not be a good idea:

Hello,

I can say that it is definitively not good.
My conclusion is that /lib /lib64 should be on the same partition as /
IF not the installation fails. It would be good to document it
if not already done.
Hence, an upgrade from Fedora 16 to Fedora 18 with
/lib on a different partiton as / will probably fails too.
Could you document it if not done with the instructions to such an upgrade.

Thank.

who does this these days and for what reason?

it makes pretty no sense on a OS with a RPM database spread
/, /usr and /var/lib over different partitions or disks because
you can not really live without one of them

I USED to install Fedora on my eeepc 901 with /usr not on the root
partition. that machine has a 4 gig SSD and a 16 gig SSD. I'd put
/ on the 4 gig, /home, /usr and swap on the 16 gig. if I put /usr
on the 4-gig partition it'd be almost full right off the bat, so that
simply adding a few more packages and it'd be full. so I moved /usr to
the other drive.

but since you can't have a (supported) separate /usr anymore I've
stopped doing that. now I just make both drives into a LVM and put
everything inside it. it feels slower that way, but at leasst it all
fits.
