using dab to create a Ubuntu 18.04 appliance

[dipe]

I wanted to start testing Ubuntu 18.04 Alpha and tried patching /usr/share/perl5/PVE/DAB.pm by adding configs for suite bionic where I found xenial

grep xenial /usr/share/perl5/PVE/DAB.pm
} elsif ($suite eq 'xenial') {
$suite eq 'xenial' || $suite eq 'wily' || $suite eq 'vivid' ||
if ($suite eq 'vivid' || $suite eq 'wily' || $suite eq 'xenial' ||
} elsif ($suite eq 'xenial' || $suite eq 'wily' || $suite eq 'vivid' ||
if ($suite eq 'yakkety' || $suite eq 'xenial' || $suite eq 'wily' || $suite eq 'bionic') {

it starts quite promising until lxc-attach bombs out with an error 127 (see below)

any hint or help would be appreciated

Thanks
dipe

I should add:

lxc-attach --version
2.0.7

after I install lxc 2.0.9 from source it bombs out right away ... rolling back.

well, it turns out that the 'ifconfig' binary is curiously missing from the current 18.04, used these steps to fix:


- create new tree rootfs-cp and put old ifconfig into rootfs-cp/sbin
- patch /uar/bin/dab so rootfs-cp tree is copied to rootfs before bootstrap
+ use File::NCopy;
$dab->ve_init();
+ my $source_dir = 'rootfs-cp';
+ my $target_dir = 'rootfs';
+ my $cp = File::NCopy->new(recursive => 1);
+ $cp->copy("$source_dir/*", $target_dir)
or die "Could not perform rcopy of $source_dir to $target_dir: $!";
$dab->bootstrap ($opts);
- install file copy perl module: apt install libfile-ncopy-perl

after that it builds me a nice container ..

ifconfig is part of net-tools. Just install it before.
