Talk:Running glibc programs

Please add the following if pertinent: https://github.com/sgerrand/alpine-pkg-glibc/

Also, would it be possible to automate adapting individual software to use musl instead of glibc?

---

I thought about the MegaCli wrapper. It should be possible to make it read the name it was called by and then launch the respective program (i.e. symlink any to-be-wrapped command to /var/lib/glibcstuff ...)

that way you get along with one wrapper script and symlinks to it in /usr/bin.

Another thing I couldnt figure is if it's important to use all 32bit versions?

And the download links for archlinux are not working because they forward wget to an https url. maybe this is some limitation in the default wget version. If i figure it out i'll do updates on this.

this is my /usr/bin/MegaCli now, using a minimal Debian install in /debian.

#we may need dev and maybe proc too to use this program

If you know how to relax grsecurity without using vanilla on Gentoo to allow PAM to not trigger a postinst error, you should edit the Gentoo section.
