With the migration to Factory, I've moved my partitions to ext4.
In my /etc/fstab, I've configure 'usual' partitions like,
/boot ext3 noatime,acl,user_xattr
swap swap defaults
/ ext4 noatime,acl,user_xattr,journal_checksum,barrier=0
/home ext4 noatime,acl,user_xattr,journal_checksum,barrier=0
which all seem pretty clear.
I'm less clear on two 'special' cases,
(1) /build, where I'll do all my development builds, source checkouts & DLs, etc
(2) /var/cache, which is simply the ususal system cache dir
For now, I've set them up initially as,
/build ext4 noatime,acl,user_xattr,journal_checksum,barrier=0
/var/cache ext4 defaults,noatime,nodiratime,data=writeback
I'm not sure these settings make sense. I've been reading online,
came across the whole 'Linus vs Ingo vs everybody' thread about the
journalling, writeback, etc etc, and have simply gotten confused.
For any / all of the dirs above, and especially the last two, what are
the recommended mount options -- in particular regarding journalling &
writeback. My goals are reliability for "my" data, and performance
for transient &/or easily re-DLable data.
