Alpine Linux: Did not find setextattr nor setxattr, cannot set extended attribute

[probonopd]

This is not of concern when using launch in helloSystem, but Alpine Linux says:

Did not find setextattr nor setxattr, cannot set extended attribute

It looks like the closest package on Alpine Linux is:

https://pkgs.alpinelinux.org/package/edge/main/x86/attr

It contains

• /usr/bin/attr
• /usr/bin/getfattr
• /usr/bin/setfattr

This seems to come from http://savannah.nongnu.org/projects/attr.
