Stange? I am just using vcheck (perl script) that goes out and checks
out software for the latest versions.
Here is an example of what happens when I run it:
http://www.tu-ilmenau.de/~gomar/stuff/vcheck/
All it does is goes out to http/ftps site, matches a regex to check for
the latest version of whatever you have, ie: sample entry:
prog util-linux = {
version = 2.11y
urgency = high
dl = no
lastcheck = "2002-12-05 06:07"
url =
ftp://ftp.win.tue.nl/pub/home/aeb/linux-local/utils/util-linux/
regex = util-linux-(__VER__)\.tar
}
This program is very useful and those warnings highly annoying. :)
Will there possibly be a /proc or kernel config option for warnings such
as these?
