There was a problem hiding this comment.
Ah, I do think the tilde is likely too strict and needed for some package names. I remember @nickanderson mentioning it I think. I checked OpenBSD and Debian and your list seems fine for those based on a simple package name search, but not on the other ways to specify package names with meta information maybe like versions and such.
Maybe a better way here is to have a default in C code that is maybe too strict and add a common attribute that can override that default so folks can make a choice without changing C code.

I also refactored the code to use a dynamic buffer when assembling the commands. Estimating the buffer size needed is error prone and can quickly lead to buffer overflows. Ticket: ENT-13535 Changelog: Title Signed-off-by: Lars Erik Wik <lars.erik.wik@northern.tech>
