Curious about tcz-symlinker

[caminati]

I toyed a bit with tcz-symlinker by Curaga, and it seems faster than busybox cpio -ias currently used  by tce-load to shadow dirtree in a tcz.
So, if my speed assessment is not wrong, I wonder why it was dropped starting from TinyCore 2.8, and I'm finding no hints by googling.

Maybe for the usual issues regarding ram usage/bloat of tcb?

Just curious, thanks in advance.

While it was a bit faster, and didn't have the issue of extensions overwriting directory permissions, cp does a good enough job while already being there.

Thanks, Curaga.
Just for fun, I did a comparison benchmark to symlink a (large) package tree using lndir (6.8 Kbytes, no deps), tcz-symlink (4.7 Kbytes) and cp -ias; each test was repeated thrice in a row (in all cases with a really negligible variance) and the last value was picked:

lndir:

Code: [Select]

real    0m 0.33s
tcz-symlink:

Code: [Select]

real    0m 0.52s
busybox cp -ias:

Code: [Select]

real    0m 0.60s
I have not investigated about how lndir behaves wrt permission and timestamps; for sure I consider the way lndir handles symlinks an advantage wrt cp, see

It would appear to ignore directories, owner group and permissions of dirs are not copied.
