By default, the upper limit to the RAM based read-only filesystem is 192 MB (uncompressed).

This can be increased by bumping the MAX_IMAGEFS_SIZE variable in two places:

https://github.com/astlinux-project/astlinux/blob/master/scripts/build#L6
--
MAX_IMAGEFS_SIZE=196608   # 192m
--

https://github.com/astlinux-project/astlinux/blob/master/project/initrd/target_skeleton/linuxrc#L6
--
MAX_IMAGEFS_SIZE=196608   # 192m
--

Then, to rebuild the initrd, simply "rm initrd.img", and the next "./scripts/build/" will rebuild the initrd.img file.

I would suggest 256m, which is 256*1024 = 262144
--
MAX_IMAGEFS_SIZE=262144   # 256m
--
