various little tidbits

My setup of SpamAssassin must have kicked in a gear because for the past
2 days, I wasn't getting any email from PLUG or from some other mail
lists such as various RedHat lists etc. I shut off spamassassin for the
time being because I don't have time to figger out what is happening.

Anyway, I am pushing myself to learn amanda - (time consuming devil it
is) and am wondering about the sensibility of some of the things that I
am doing.

1 - I was getting tired of prefacing all my commands with the /usr/sbin
prefix so I created a .bash_profile and put the various paths
/usr/bin:/usr/sbin:~/bin so I can be lazy (sort of like being root).
Does this represent a security problem?

2 - Perhaps more basic - the user amanda is used to run the various
programs - mostly /usr/sbin/amdump with is setuid root and obviously
amanda uses a bash shell whereas most of the 'daemon' users don't have a
login shell (for obvious reasons). How much of a security issue is this?

3 - Perhaps this is more philosophical...why does all tape backup
software suck?
