Building of rootfs doesn't work with file:// repositories

[jekhor]

We need to mount  file:// repositories into chroot, probably.

Build environment is able to use http://, ftp:// and other networked repositories to fetch the following packages:

• cross-compilation packages for build environment itself
• target packages for creating rootfs

Using file:// repositories does not work though, as those repositories are not propagated from outside to chroot and further to inner chroot. This could be fixed by proper mount --binding in enter script and cross-shell.

Simple patch for accessing exterior local repos from chroot dev environment.

[EvanKroske]

I wrote a simple patch to access local repositories in the main environment from the chroot development environment. It cleans up after itself if the chroot dev environment is exited properly, but it leaves mounted directories if the shell window is closed. I'm working on a more robust version now. Are there any obvious bugs in my patch?

[dottedmag]

Nice one, clean and simple.

• I'd change removing empty directories to rmdir "$dir" 2>/dev/null || : to avoid relying on ls.
• To make sure everything is cleaned up use trap and handle SIGHUP, SIGTERM etc.
• Add some kind of locking, so subsequent calls won't mount the repositories twice. It is ok to have a racy locking (just test && touch) in this case, as enter is expected to be used interactively.

A bit of nitpicking:

• Please don't quote paths without spaces inside, like "/etc/mtab"
• if foo; then style is a bit more compact
• Variables should be c_sty_le, not camel cased.

Final patch for the enter script. Cleans up mounted local repos if script is interrupted.

[EvanKroske]

The new patch cleans up the local repositories if the script is exited or user-interrupted (Ctrl + C), but it can't cope if the terminal window is closed or killed. I don't think the KILL signal can be caught by a bash script. This patch also complies with the style guidelines mentioned above.

cross-shell now mounts local repositories mentioned in the sources.list file of the target fs (the e-reader).

[EvanKroske]

Added functions for mounting and unmounting repositories.
