Hey guys,
I was setting up a test build host to look at what it would take to get
our product on FC4.
After a couple of tweaks to the build and installation script I was up
and running. And running straight into a weird problem.
For some reason my format_device function in the bash script was failing
on any of the mkswap/mke2fs commands. It was claiming that it couldn't
find /dev/<device>.
There's nothing wrong with the commands. The same script runs fine on
other build hosts here in the office. So I decided to dig a little
further. I wrote a test script and managed to replicate the problem.
The script basically is nuking the target devices partition table and
using parted to rebuild it for our install, then using mkswap/mke2fs to
format the new partitions.
The problem is with udev in that it seems to take an age to recognise
the changes performed by the parted commands. Even running from the
console, it seems to take between 10 to 12 seconds or so to pick up the
partition changes.
Brute force fix was to make a call to /sbin/start_udev which triggered a
a refresh. I'm sure there must be a better way to trigger this, so if
you've any suggestions, then please pass them on.
