Hi,

I'm sorry to report an 'important' bug just one day before busybox migrates to forky.

The Debian installer udeb 'live-installer.udeb' uses the 'chdir' command (instead of the more modern 'cd'), which is no longer provided by busybox 1.38.
Therefore it is not possible to use a live image to install Debian.

Found by openQA:
https://openqa.debian.net/tests/536370#investigation

The 'diff_sut_packages_to_last_good' points to busybox-udeb as a cause for the failing installation.

I propose to block the migration of busybox to forky, while doing both kinds of fixes:
1) re-enable chdir in busybox
2) change from chdir to cd in live-installer.udeb

With kind regards,
Roland Clobus
Co-maintainer of the Debian live images

Control: reassign -1 live-installer/58

chdir was a non-standard extension in dash.  This is a problem in
live-installer itself.

Bastian

Control: severity -1 serious
Control: clone -1 -2
Control: reassign -2 live-installer/58

The reporter did say that in their original message.

Not sure why the above clone command didn't work, but let's have this as
RC to prevent busybox from migrating until live-installer is fixed.
