1) Putting /tmp on a mounted file-system invites trouble.
Some Install scripts presume the work area -- under /tmp --
is on the same file-system as the target areas (/bin, /usr/bin,
/lib, /usr/lib, etc...). This is fact -- I don't and never did
advocate it. Their use of 'ln' instead of 'mv' means they will
fail if you run this from a mounted /tmp.
2) Putting /usr/spool on a mounted file-system invites trouble.
If I recall correctly, some of that wonderful LP code
presumes they can 'ln' the files from wherever to the
spool area. I haven't experienced this, but was told
so long ago in a distant galaxy.
30 MB! I'd recommend just using it as a spare /u2 [user file] area.
I have NOT heard any warnings about mounting /usr/tmp -- if enough
of your programs use this it might be worth it.
