Add keepalived package

[tchekoto]

Hello,

Thank you for your great work, I use it on my QHora 301w and it has been working flawlessly for months.
Can you please add the package keepalived in your image (I cannot install it from package manager)?

Thanks :)

Hi @tchekoto

I try to keep the version as vanilla as possible, adding only packages that are essential or that everyone agrees.

Here is the link to the Telegam group: LINK (Spanish is spoken in the group, but you are welcome :)
