Clear Linux installation on bare metal as of Version 28210 is not as simple as as it is on most modern GNU/Linux distributions -- not because its ncurses type installer is particularly difficult to use, but because of its lack of flexibility in specifying installation target partitions.
In this article I provide a description of this limitation, amd links to a description to how I prepared my Acer V15 Nitro laptop to work around the limitation (compared to other distributions), to a description of Clear Linux's pre-installation resources, and to the review of Clear Linux Version 28210. Finally I present screenshots of the installation steps running the installer in the Live ISO Environment.
Note: Although this article was published on June 4, 2019, it was based on use of Clear Linux 28210 and its updated builds between March 8, 2019 and April 26, 2019. A new GUI installer has been released by Clear Linux recently and is included in its installation images. This may solve some of the limitations I encountered during installation of the distribution, but from the screenshots I have seen, it seems to be only an interface change.
While Clear Linux is one of the more innovative GNU/Linux distributions, especially when used for its primary original purpose of cloud centric and virtual or container applications, at this point in its development -- at the time of this writing at Version 28210 -- it is not possible to select installation target partitions on more than one disk. For example, it is not possible to specify a root partition on a primary SSD and the home and swap partitions on a secondary partition. Also the disk selected for installtion will be completely deleted, and specified partitions created, even if only selecting existing partitions for reuse in the installation.
The Clear Linux documentation does specify that the first installation on a computer must be Clear Linux with other distributions optionally installed after Clear Linux. (Of course if it is the first installation there will not be anything that can be deleted.) This requirement does not exist in any other GNU/Linux distribution I can think of using, where at worst the EFI System partition or an existing swap partition if specified for an installation is reformatted.
In order to try Clear Linux on bare-metal on my preferred computer, I took the drastic step of first relocating the OEM Windows installation and then allowing the Clear Linux installer to delete the partitions on the primary SSD, after which I reinstalled two other distributions on the primary SSD.
You can read the review for more on my experience with CLear Linux, and the preliminary steps before installation, including verifying the Clear Linux optimizations for the Intel Architecture are available on your computer, but below are screenshots of using the installer in the Live ISO Environment.
Some notable points on the installation using the installer provided with the Live ISO:
If one is willing to accept that the Clear Linux installer will completedly delete the chosen disk to install the distribution, the actual installation using a recent ISO is quick and simple, the only problem in my view being the afore mentioned inflexibility.
Unfortunately, in installing and using Clear Linux it is obvious that its limitations stem from its origins as a platform for specialized cloud, virtual machine, and container uses -- in the case of the installtion a platform where only one filesystem is necessary. However, while not there yet, it does seem that the development team does care about making the distribution more usable on the desktop -- case in point the addition of a Live ISO (still a beta at this point) -- to the selection of installation ISOs.
