I am assuming you are asking about "The Vagabond" by Robert Louis Stevenson. If this is not correct, please submit another question with more identification.
A "vagabond" is a person who is homeless by choice, one who wanders the world as s/he wills with complete freedom to go and do as s/he chooses. The vagabond speaking in the poem is expressing the desire for and the pleasure in having that lifestyle.
There is no concern for shelter - having the sky above is enough. "Bed in the bush" is adequate for a place to rest. Weather is not a problem, regardless of wind or the cold of autumn or winter. The vagabond isn't concerned about having people for companions or about making money, but wants to spend his/her life exploring the world. There is no interest in settling in any one place or building any kind of connections that might hold one to one area. "All I seek, the heaven above and the road below me."
Robert Louis Stevenson's (1850-1894) poem "The Vagabond" celebrates the glorious freedom and independence of a tramp's life. All the four stanzas of "The Vagabond" repeatedly emphasize the unrestrained joys of an independent life in the outdoors free from all its hassles.
All that the vagabond is interested in is a life of unlimited travel. He wants to completely avoid all human associations - "nor a friend to know me."All that he wants to do is travel and travel from one place to another without any restraint whatsoever, not concerned about the weather or material wealth or possessions or anything else around him:
"Give the face of earth around,
And the road before me.
Wealth I ask not, hope nor love,
Nor a friend to know me;
All I ask, the heaven above
And the road below me."
He would like to spend his entire life in the outdoors even in the cold autumn and winter months with the sky as his roof:
Not to autumn will I yield,
Not to winter even!
Most importantly, he wishes for a completely carefree life and is not bothered or frightened about death at all:
Let the blow fall soon or late,
Let what will be o'er me
