gLinux is a
Debian Testing-based
Linuxdistribution used at
Google as a
workstationoperating system.[1] The Google gLinux team builds the system from
source code, introducing their own changes.[2][3][4][5][6][7][8] gLinux replaced the previously used
Ubuntu-based distribution,
Goobuntu.[9] gLinux is usually installed by loading into a bootstrap environment when it is first booted up.[10] When it is started, the root files are unpacked and the
Debian installer starts to perform the installation.[10] According to a former user of the OS, it uses the
Cinnamon desktop environment.[11] As of 2024, only the GNOME desktop environment is fully supported. Over the years,
Google has focused on speed, scale and data, which is the thought process that allowed them to move to gLinux.[12]Google used
Ubuntu before switching to gLinux; however, the two years of security updates it provided meant that planning for the next upgrade would take close to a year.[13]
