you probably won't find tons of entry level gigs offering relocation assistance, but if you can get something remote, or within a reasonable commuting distance of where you live now, then you can save up for a few weeks or a month (assuming you have low/no cost of living at home) and probably have enough to put down a deposit for a place if they aren't too picky about income history. Worst case maybe you need 3 months consistent income or a cosigner.

I assume this is in the US?

There's no "one simple trick" type opportunity that I know of, but if you look long enough on job sites and cast a very wide net of applications (apply for shit even if it is above/below your experience level, or not quite in your area/specialty) you can probably get something. Do some research on what keywords or AI garbage or whatever people are doing to get their resume to an actual human these days. Having linux experience isn't that common so that's probably a good area to focus on, devops, sysadmin, cloud infrastructure, or linux specific/adjacent developer jobs all could use that experience rather than having to train a fresh grad who has the same education as you but no real life linux experience.

The only "one simple trick" thing I can think of is leveraging your social connections. Ask around, both for leads on specific jobs/to make introductions, and to just get the word out in case they hear about something after you talk to them. Talk to family friends, friends in the industry, friends in adjacent industries, basically anyone you know, even tenuously, that is gainfully employed tbh. They may have leads for you, or get your foot in the door with someone else that they know (skipping the painful process of repeatedly applying for jobs and repeatedly getting ghosted that seems to be universal now), or just offer more tailored advice than strangers online can. you even can reach out to online friends/communities, since you might not know a lot of techy people IRL, and many of them will be employed in related industries. As much as applying for jobs is a headache and a power imbalance that favors the employer, it is still a headache for small employers to hire as well, so having any personal connection that skips going through the various job listing sites will be mutually beneficial.
