Subject: [PATCH v3 4/5] Use symlinks when importing debian packages to sbuild chroot
Date: Fri, 20 Jan 2023 08:31:05 +0100 [thread overview]
Message-ID: <20230120073106.5453-5-ubely@ilbers.de> (raw)
In-Reply-To: <20230120073106.5453-1-ubely@ilbers.de>
When building packages, sbuild downloads missing dependencies from
debian mirros. In order to reduce network consuming and have in DL_DIR
every package downloaded by sbuild, we additionally import/export
local debian packages to/from apt cache in schroot upper layer.
Since hardlinks between package WORKDIR and apt cache in schroot
don't work (different filesystems), will use symlinks when importing
debs to schroot (--chroot-setup-commands) and copy with dereference
when exporting them back (--finished-build-commands).
