Subject: fs/ext2: use a post-gen hook rather than a post-target rule
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=03b6b7952f7fad486d0c130acae08e7561739dae;p=buildroot.git

fs/ext2: use a post-gen hook rather than a post-target rule

post-target rules are probably not resilient to parallel builds, given
that they do not depend on the image being generated first.

Beside, we already have a mechanism for running stuff after the
filesystem is generated, and that's called post-gen hooks.

Use those hooks.

Note: this basically reverts 75b6303 (rootfs-ext2: make the symlink as a
_POST_TARGET) since we've now re-introduced post-gen hooks.
