[ale] /tmp set to read-only on boot (need help)

[Ryan Fish]

No changes or additions other than some updates from RH.  The last time this
particular box was booted it took quite a while for it to come back online.
I was not an the console at that time so I did not see any messages that may
have been displayed.  I've checked dmesg and didn't see anything jump right
out as being bad either.

Your problem seems to be that the root filesystem is mounted
read-only.  "mount -o rw,remount /" might work, but it's
strange that / is not getting remounted rw after boot.

Have you changed anything about the disk configuration of
this machine? Added a drive or something?
