No, there seems to be something that happened with yesterdays rawhide update.
I just rebooted and got the message that my home dir did not exist.  I
went to a virtual term and looked to see what ws up.  This is what I got:

Filesystem            Size  Used Avail Use% Mounted on
/dev/hda1              97M   18M   75M  20% /boot
none                  244M  184K  244M   1% /dev/shm
/dev/hda5              97M   18M   75M  20% /home

Well that is weird.

This is my fstab:
# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /dev/shm                tmpfs   defaults        0 0

none                    /sys                    sysfs   defaults        0 0
/dev/hda3               swap                    swap    defaults        0 0
/dev/hdc                /media/cdrecorder       auto   
pamconsole,fscontext=system_u:object_r:removable_t,ro,exec,noauto,managed
0 0
/dev/scd0               /media/cdrecorder1      auto

A ls of /home showed that it was empty.  So I mounted it. and it was there.

But I did not see anything in /boot.  /boot is hda1, but / is hda2.  The
size for /boot is correct, but when I went to /boot it was empty.  Looking
at / showed that it was mounted as /boot.  I mounted /boot ok, and the
files are there, but the latest df shows:


[bpm]$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda1              97M   18M   75M  20% /boot
none                  244M  184K  244M   1% /dev/shm
/dev/hda5              26G  6.2G   19G  26% /home
/dev/hda1              97M   18M   75M  20% /boot
[bpm]$ cd /
[bpm]$ df -h .
Filesystem            Size  Used Avail Use% Mounted on
-                     9.7G  5.2G  4.0G  57% /


So I'd say something is rotten.
