I got the /home pointing to /opt/Local/home just fine - but ...now
doing mail:
Having just been pretty pleased with myself for getting my system
running I now find a problem.... This question was also posted to
Fedora list.
First I have my home directory bind mounted from /home
to /opt/Local/home with no problems, and I bind mount using an fstab
entry like /opt/Local/home /home ext3 bind 0 0
The context for /home is system_u:object_r:home_root_t:s0
and for /opt/Local/home it is the same.
The mount works fine during boot - so I tried the same with my mail.
I have an fstab entry
/opt/Local/spool/mail /var/spool/mail ext3 bind 0 0
The context for /var/spool/mail is system_u:object_r:mail_spool_t:s0
and for /opt/Local/spool/mail it is also the same.
I can manually do
mount /var/spool/mail and the bind mount works fine.
However on boot I get an avc denial, with kernel: type=1400 and
and avc: denied {mounton} .... comm="mount" path="/var/spool/mail"
dev=sda5 ino=419655 scontext=system_u:system_r:mount_t:so
tcontext=system_u:object_r:mail_spool_t:so class=dir
I am not sure what to change to make this work?
First temporarily unmount the bind mount:
# umount /var/spool/mail
Then change the context of the original /var/spool/mail to make it
suitable for use as a mount point:
# chcon -t mnt_t /var/spool/mail
Mount at boot should now work. You can simulate this without actually
rebooting by doing:
# service netfs start
Cheers, Paul.
